Buying a DVR camera system is easier when you know what each part does before you pay for it. Too many boxes come home missing a hard drive, the right power supply or enough cable for a steep Simon's Town property. This checklist walks you through every piece so the install day goes smoothly.
Quick answer
Before buying a DVR camera system, decide how many cameras you need now and later, then pick a recorder with spare channels. Check it includes a surveillance hard drive, a proper power supply, outdoor-rated cameras for salt air, enough coaxial cable and connectors, and a backup power plan. Plan internet access if you want to view it on your phone.
What's inside a DVR camera system
A DVR (digital video recorder) is the box that records and stores footage from wired cameras. The cameras connect to it with coaxial cable, much like a TV aerial lead.
A full kit usually has five parts:
- The recorder. Its channel count tells you how many cameras it can take.
- Cameras. Dome or bullet style, each with its own lens and night vision.
- A hard drive. Some recorders ship with one, many don't.
- Power. A central power supply or separate plug-in adaptors for each camera.
- Cable and connectors. Often the part that runs short on hilly sites.
If one of these is missing on the day, the job stops. That's why we check the box contents with you before we start our CCTV installation.
DVR or IP camera system: decide this first
The biggest choice comes before brand or price. A DVR camera system uses coaxial cable. An IP camera system uses network cable and a recorder called an NVR.
| Question | DVR (coaxial) | IP system (network cable) |
|---|---|---|
| What cable does it use? | Coaxial, sometimes with a separate power lead | Network cable, often carrying power too |
| Can it reuse old cabling? | Often, if old coaxial runs are still sound | Usually needs new cable pulled |
| Picture detail | Good for most homes and entrances | Usually sharper, better for zooming in on detail |
| Best fit | Upgrading an older system on a budget | New builds, guesthouses and bigger properties |
For an older Victorian building along St George's Street, reusing existing coaxial runs can save a lot of drilling through thick walls, which we cover in our guide to mounting on heritage walls. For a renovated guesthouse in Glencairn, an IP camera system may be worth the extra cabling.
4 channel DVR or 16 channel DVR: count your cameras
Each channel is one camera. Most people underestimate how many they'll want once the first few are up.
When a 4 channel DVR is enough
A 4 channel DVR suits a small home or flat with one gate, one front door and a back yard. It's also fine for a single holiday flat where you only want to watch the entrance and parking.
When to step up to 8 or 16 channels
A 16 channel DVR makes sense for a guesthouse, a large home with outbuildings or a property on several levels. Homes stacked up the mountainside in Murdock Valley or Welcome Glen often need cameras on each level, plus one on the street.
Technician tip
Buy at least two more channels than you need today. Adding a camera later is easy. Swapping a full recorder for a bigger one means starting the setup again.
Cameras that survive the False Bay coast
Cameras here face things inland cameras don't. Salt air, strong south-easters and sudden light changes all wear on cheap housings.
- Outdoor cameras have a high weatherproof (IP) rating on the box.
- Housings and brackets are metal or tough plastic with rust-resistant screws.
- Night vision is good enough for late afternoon, when the mountain shadow arrives early.
- The lens angle suits the spot: wide for yards, narrower for a long driveway.
- Mounts are solid enough not to shake in the wind and blur the picture.
Salt eats away at metal joints and connectors faster than most people expect. Our salt air corrosion guide was written for dishes, but the same rust shows up on camera brackets near Boulders and the harbour.
Storage, power and backup for your DVR camera system
This is where cheap kits cut corners. Check these three things carefully.
Hard drive
Use a surveillance-rated drive, built to record all day. How long footage lasts depends on the number of cameras, the picture quality and whether you record all the time or only on motion.

Power supply
Coaxial cameras need their own power. A single, fused power box near the recorder is neater and safer than a tangle of adaptors behind a cupboard.
Backup power
Without backup, the system goes blind exactly when the power fails. A small UPS on the recorder, router and power box keeps it recording through short outages.
Safety first
Running cable along gutters, roof edges and steep stairways means ladders and heights. Mains power supplies also need careful, safe wiring. Leave both to a trained technician rather than doing it yourself.
Cable runs on steep Simon's Town properties
On a flat plot, cable is simple. On a hillside in Da Gama Park or Castle Hill, the recorder might be two floors away from the gate camera.
- Walk the property and mark where each camera will go.
- Measure the route from each spot to the recorder, following walls and eaves, not a straight line.
- Add extra length for corners, drip loops and a little slack at each end.
- Choose sealed, outdoor-grade connectors for anything outside.
On heritage buildings, plan routes that avoid drilling into decorative facades. Check with the owner or managing agent before anything gets fixed to the front of the building.
Remote viewing and your home network
Most people want to check their cameras on a phone. That needs the recorder plugged into your router and a stable internet connection.
If the router sits in the main house and the recorder is in a cottage or garage, you may need a network cable or a wireless link between them. Our WiFi and network setup team handles that, and our guide to extending WiFi to a cottage shows the usual options.
Holiday homes and guesthouses get the most out of remote access. Read our post on remote CCTV viewing for owners who are often away.
Good to know
A DVR records to its own hard drive, so it keeps working if the internet drops. You only lose the live phone view until the connection is back.
Your pre-install DVR camera system checklist
Tick these off before booking the install. It saves a second trip and a second bill.
- Number of cameras now, plus two spare channels.
- DVR or IP system chosen to match your cabling.
- Surveillance hard drive included or bought separately.
- Power supply and UPS planned.
- Outdoor cameras rated for salt and wind.
- Cable length measured along the real route.
- Router location and internet plan sorted for phone viewing.

DVR camera system: FAQs
What is a DVR camera system?
It's a set of wired security cameras that connect to a digital video recorder with coaxial cable. The recorder saves footage to a hard drive and shows it on a screen or phone app. It's a common choice for homes upgrading older analogue CCTV.
How much does a DVR camera system cost in Simon's Town?
It depends on the number of cameras, the recorder size, the hard drive and how long and tricky the cable runs are. Steep sites and heritage walls take more time. Ask our team for a current quote after a quick look at the property, since we always quote first.
Is a 4 channel DVR enough for a house?
For a small home with one gate, a front door and a yard, often yes. Many families add cameras later, though, so an 8 channel recorder gives room to grow without replacing the box. Count every entrance and outbuilding before deciding.
Does a 16 channel DVR come with a hard drive?
Some do and many don't, so check the box or ask before you pay. If you buy one separately, choose a surveillance-rated drive. Its size decides how many days of footage you keep.
Can a DVR camera system work without internet?
Yes. The cameras record straight to the hard drive in the recorder, so footage is saved even with no internet. You only need a connection to watch live or play back footage on your phone while you're away.
